González stood 2.32 m (7 ft 7 in)[1][7], making him the tallest Argentine basketball player in history.[7][9] He started his career with the youths of Hindú Club de Resistencia at the age of 16 (and already 2.15 m (7 ft 1 in) tall).[7] Subsequently, León Najnudel, then coach of the Argentine national team, recommended the board of Gimnasia y Esgrima La Plata to sign the player for the team's Argentine second division roster.[7] During 1986, González helped Gimnasia achieve promotion to the Argentine first division.[7]
The player then signed for Sport Club Cañadense, but saw little action
due to an injury that left him out of the fields for 9 months.[7]

In 1988, González was drafted by the Atlanta Hawks in the third round of the NBA Draft, after the American team bought the player's rights from his Argentine team for a 30,000 Argentine australes fee.[1][7] However, he was unable to adapt to the physical demands of NBA basketball.[7]

In 1989, Hawks owner Ted Turner offered González a job as a professional wrestler
with another of his ventures, World Championship Wrestling (WCW). After
a year of training, González was introduced to fans as El Gigante on
May 19, 1990 at the pay-per-viewCapital Combat. Wearing shorts, he competed as a fan favorite and was billed as being close to eight feet tall.

González competed as "Giant Gonzales" during his time in World Wrestling Federation (WWF) as a villain, managed by Harvey Wippleman,
González grew a beard and wore a full body suit that featured
airbrushed muscles with bushy hair attached. He was introduced at the Royal Rumble in January 1993, where he eliminated Wippleman's nemesis The Undertaker from the Royal Rumble match despite not being an official participant.[2] Gonzalez lost to The Undertaker at WrestleMania IX by disqualification after he knocked Undertaker unconscious using chloroform. This remains the only instance where the Undertaker has not had a decisive victory in his WrestleMania streak.[2] After another loss to The Undertaker at SummerSlam, Wippleman berated Gonzalez leading Gonzalez to turn on Harvey Wippleman.[2] Though the foundation was later set for a feud with González and Adam Bomb, it never truly began. His last appearance in WWF was on the October 4, 1993 episode of Monday Night Raw in a 20-man battle royal for the Intercontinental Championship. Gonzalez's WWF contract expired three days later.

After his departure from WWF, González wrestled in the Japanese promotions New Japan Pro Wrestling and WAR
(Wrestle and Romance) until his retirement from wrestling. His last
singles match was in Sendai, Japan on February 8, 1995, against The Great Muta and his last Japan tour for WAR in December 1995.
